Answer 1

Question :

To find height of a triangle

Answer :

Given :

• Area of triangle is 3 ha

• Its base is 200 m

• height = ?

${\underline{\boxed{\bf{area \: of \: triangle \: = \frac{1}{2} \times b \times h}}}}$

• b = base
• h = height

In this question , the area of triangluar farm is mentioned in ha. 'ha' is the symbol of Hectare.

We know that,

1 ha = 10000 square metres

So, here 3 ha is 30000 square meters . Hence, Area is 30000 m².

$\sf\rightarrow \: area \: = \frac{1}{2} \: ( b \times h )\: \\ \\ \sf \rightarrow \: \frac{1}{2} \times( 200 \times h) = 30000 \\ \\ \sf\rightarrow \: \frac{1}{2} \times 200h \: = 30000 \\ \\ \sf \rightarrow \: 100h \: = 30000 \\ \\ \sf\rightarrow \: h \small = \frac{30000}{100} \\ \\ \bf\rightarrow \: h \: = 300$

Hence, height is 300 m ( a )

Let's verify ::

$\sf = \: \frac{1}{2} \times b \times h = 30000 \\ \\ = \sf \frac{1}{2} \times 200 \times 300\: = 30000 \\ \\\sf = \frac{1}{2} \times 60000 = 30000 \\ \\ \sf \: 30000 = 30000$

$\bf \: LHS \: = \: RHS \:$

Note : 3 ha(hectare) is 30000 m².

Thus Solved !!
